There is no fallback on group id, if no group title, no legend is
displayed

This is same as "xhtml_style: display form groups legends", but applied
to ERP5JS.

The returned type of `group_list` changed in the API, it use to be a
list of lists with 2 elements: group id (str) and field list (list),
it is now a list with 3 elements: group id (str), field list (list)
and group title (str).

There's now a new `legend` element in the DOM, only when the group has a
title.

For erp5_web it is possible to define form groups following a naming
rule "group_id (Group Title)" and "Group Title" is displayed in a legend,
according to this comment in form_render.zpt:

> It is possible to specify a group id and a group title by naming a group following the
>   "group id (Group Title)" pattern. In this case the group id will be used as fieldset css
>   class and as tag id. The group title will be used as a legend for the fieldset. If no group
>   title is found, we use group id as title.

For historical reasons, the legend was hidden, this feature was only
used in erp5_web, but this does not seem bad to enable it in
erp5_xhtml_style as well.

At the moment, this is not used much, this script

```py
for sf in context.getPortalObject().portal_skins.objectValues():
  for f in sf.objectValues():
    if not hasattr(f, 'get_groups'):
      continue
    for group in f.get_groups():
      if '(' in group:
        print('/'.join(f.getPhysicalPath()[1:]), group)

return printed
```

when running on a site with many business template installed yields

and this does not look bad when viewing the forms.

only the case without an URL column was properly handled

If erp5_credential is installed in ERP5, we will use the dialog from erp5_credential instead of accessing portal_password directly.

- setting configurator header link
- allow auto_sync when adding opml
- update form title
- fix landing page
- fix dispatch
- fix form naming
- fix form and fields naming (coding style tests)

   Otherwise, alarms to fetch what was paid (status) don't work.

  Mistake was probably there because copy and paste

Raise an exception instead of casting to string unhandled search values,
because it's more likely that caller accidentally passed a wrong value.

Some general changes to test framework and shared test code

See merge request !1936

this happens with new ghostscript, but this does not seem a critical
problem.

The test was only testing with empty cache

This should not happens, but if this happens we should not just return
in the middle of the loop, because this returned value is not used,
so we would just silently edit partially.

The first commit of this merge request was introduced for zope4py3 branch but it revealed issues on py2 as well, i.e. we don't have roles in auto-generated tester methods.

If a transaction is selected but instead of having accounts as
source/destination on lines it acquires the organisation set as
source/destination on the transaction, this causes an AttributeError
getGapList when trying to use this organisation as an account.

To fix this, adjust the getMovementHistoryList parameters to select only
lines using accounts, by passing node_uid, which is O(n) on the number
of accounts, but the number of accounts is not supposed to be too large
and other reports also do this assumption.

This prevents one failing test to make all subsequent tests to fail

this is removed from python3, it was not so useful here either

use sys.maxsize, see discussion on
nexedi/erp5!1751 (comment 203735)

assertCountEqual is the new python3 name.

Implement this in backportUnittest.py and also move the existing similar
patches (assertRaisesRegex and assertRegex).

  - move the logic of uploading to WebDAV server here instead of the
 generated bin/runUnitTest wrapper
  - run a new `coverage_report` which will
    - download all coverage data from WebDAV server
    - combine the data
    - run html report, saved in log folder
    - print text output in the text output.

This `coverage_report` test waits for other tests to finish uploading
data, we could extend test node distributor to distribute this test at
the end.
